symbols used to indicate where a group starts and ends, for example brackets

The symbols used to indicate where a group starts and ends, such as brackets, are called delimiters. There are various types of delimiters used in different contexts.

1. Parentheses or round brackets ( ) : They are used to group elements and operations in mathematics and programming. For example, in the equation (2+3)*4, the operations within the parentheses are performed first.

2. Square brackets [ ] : They are often used in programming to denote an array or list. For example, in Python, a list can be defined as list = [1, 2, 3].

3. Curly brackets { } : They are used in programming to denote a block of code. For example, in C++, a function could be defined as void function() { //code }.

4. Angle brackets < > : They are used in programming and markup languages to denote tags. For example, in HTML, a paragraph is denoted by <p>text</p>.

5. Quotation marks " " or ' ' : They are used to denote a string in programming. For example, in Python, a string can be defined as string = "Hello, World!".

These are just a few examples. The specific use of these delimiters can vary depending on the context and the specific rules of the language or system in which they are used.
